Specifications

If no sections are available in an old public sewer network to which a branch is to be added for the purposes of home connections, the branches are installed as follows:

1. A hole is made in the main line using a drilling machine
2. Ring B is placed inside the hole
3. Add the lard
4. The tail of the subpiece enters the B ring slot

Where we obtain a tight connection taking into account the following:

A- The branch piece must not protrude inside the main pipe and its end must be identical to the curvature of the inner surface of the main pipe.

B- There are two types of drilling tools, one for a 45-degree incline and the other for a 90-degree straight hole. Both types can be installed on an electric machine or a pneumatic machine.
